Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked,
the handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
You can use the keyless entry system.
You can use your key.
You can also use the manual lock/unlock levers
(from the inside).
To lock the door from the
inside, slide the manual
lock/unlock lever rearward.
To unlock the door, slide
the manual lock/unlock
lever forward.

2-7
Power Door Locks
Press the raised side of
the switch, marked L on
either front door to lock
all the doors at once.
Press the recessed side of the switch marked U to unlock
all the doors at once.
The power door locks will operate at any time without
the ignition being on.
The power door locks are also programmable.
See ªProgrammable Automatic Door Locksº following.
Operating the power locks may interact with the
theft
-deterrent system. See ªContent Theft-Deterrentº
in the Index.
Programmable Automatic Door Locks
Your vehicle is equipped with an auto lock/unlock
feature which enables you to program your vehicle's
power door locks.
Your vehicle left the factory programmed to lock all
doors when the vehicle is shifted out of PARK (P) and
the engine is running and then unlock all of the doors
when the vehicle is shifted into PARK (P). You can set
the automatic lock feature to lock the doors you choose
when the vehicle is shifted out of PARK (P) and unlock
the doors you choose when the vehicle is shifted into
PARK (P). You can also choose to have none of
the doors lock or unlock. The following instructions
detail how to program your door locks. Before you
enter the program mode, you will want to choose
one of the programming options following the
programming instructions.

2-8
To enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then pull the turn
signal/multifunction lever all the way toward you
and hold it there while you perform the next step.
2. Turn the key to RUN and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock.
3. You are now ready to program the automatic
door locks. Select one of the four programming
options listed above, and follow the instructions.
You will have 30 seconds to begin programming.
If you exceed the 30 second limit, the locks will
automatically lock and unlock to indicate that you
have left the program mode. If this occurs, repeat
the procedure beginning with Step 1.
You can exit the program mode any time by turning
the ignition to RUN (the locks will automatically
lock and unlock to indicate that you are leaving the
program mode). If the lock/unlock switches are not
pressed while in the programming mode, the current
auto lock/unlock setting will not be modified.The following is a list of available programming options:

All doors lock/Driver's door unlocks only: Press
the lock side of the power lock switch on the
door panel once and then the unlock side once.

All doors lock/All doors unlock: Press the lock
side of the power lock switch on the door panel once,
and then press the unlock side twice (this is the
factory setting).

All doors lock/None of the doors unlock: Press the
lock side of the power lock switch on the door panel
once, and then press the unlock side of the switch
three times.

No doors lock/None of the doors unlock: Press the
lock side of the power lock switch on the door panel
twice. This turns off the automatic lock feature.
See your dealer for more information.
Lockout Prevention
To protect you from locking your key in the vehicle,
this feature stops the power door lock from locking
the driver's door when the key is in the ignition and a
door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock.

2-9
Child Security Locks
You will find a security lock lever on the inside edge of
each rear door. Your vehicle may be equipped with one
of the two labels shown.With this feature, you can lock the rear doors so they
can't be opened from the inside by passengers. To use
the security locks do the following:
1. Open one of the rear doors.
2. Move the lever up to engage the security lock.
Move the lever down to disengage the security lock.
3. Close the door.
4. Do the same thing to the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on,
unlock the door and open the door from the outside.

2-10
Keyless Entry System
You can lock and unlock your doors from about
3 feet (1 m) up to 30 feet (9 m) away using the remote
keyless entry transmitter supplied with your vehicle.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.

2-11
Operation
UNLOCK: Pressing this button once will unlock the
driver's door. The parking lamps will flash and the
interior lights will come on. Pressing UNLOCK again
within three seconds will cause the remaining doors to
unlock. The parking lamps will flash and the interior
lights will come on.
LOCK: Pressing this button once will lock all of the
doors. Press LOCK again within three seconds and the
horn will chirp.
Operating the keyless entry transmitter may interact
with the theft
-deterrent system. See ªContent-Theft
Deterrentº in the Index.
Remote Panic Alarm
When the button with the horn symbol on the keyless
entry transmitter is pressed, the horn will sound and the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for 30 seconds, or starting the vehicle.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum of four
transmitters matched to it.

2-12
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.
To replace the battery in the keyless entry transmitter,
do the following:
1. Insert a dime or similar object in the slot between the
covers of the transmitter housing near the key ring
hole. Remove the bottom by twisting the dime.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
